The mum-to-be took to Snapchat to give fans a sneak peak at how the engaged couple are coping after recently confirming they are expecting their first child together.

In a post on the photo and video sharing app, the pair are seen running errands around Los Angeles - including making sure her pregnancy cravings are taken care of.

Rather than anything particularly unusual, it appears the star simply wanted chicken salad sandwiches from Porta Via in Beverly Hills.

Chyna shared a clip of her tucking into the tasty treat, with both her and her partner transformed into babies with a filter on the app.

It comes after the star debuted her baby bump last night at the launch of her emoji range - Chymojis - as she posed with her baby daddy and future husband at the lavish app launch, just days after the happy news was revealed.

Stroking her slight bump, the 28-year-old former fiancé of Tyga was practically beaming as she cuddled up to Rob and looked very happy to be expecting her second child.

Usually a fan of the skin-tight look, Chyna appeared to come over all earth mother as she sparkled on the red carpet in a black sheer dress over black leggings.

Looking far more glamorous than we've seen her look in a while, the mum-to-be teamed the ensemble with flowing braided blonde locks.

Maybe Chyna is having a makeover now she's becoming an official Kardashian?
